NEW ORLEANS — Three men have been arrested in the fatal hit-and-run of an off-duty police officer early Sunday morning, police said.

According to court documents, 25-year-old Justin McKey turned himself in to authorities on Monday about 3:30 p.m. and admitted to driving the 2013 Porsche Panamera that hit and killed officer Rodney Thomas. He was booked on charges of manslaughter and hit and run causing a death or serious injury, and is being held on a $50,000 bond, records show.
